In this spectral region, photoredox catalysis represents the most efficient polymerization method, yet it relies on the use of heavy\u2010atoms, such as precious metals or toxic halogens. Herein, spin\u2010orbit charge transfer intersystem crossing from boron dipyrromethene (BODIPY) dyads bearing twisted aromatic groups is shown to enable efficient visible light polymerizations in the absence of heavy\u2010atoms. A \u22485\u201315\u00d7 increase in polymerization rate and improved photostability was achieved for twisted BODIPYs relative to controls. Furthermore, monomer polarity had a distinct effect on polymerization rate, which was attributed to charge transfer stabilization based on ultrafast transient absorption and phosphorescence spectroscopies. Finally, rapid and high\u2010resolution 3D printing with a green LED was demonstrated using the present photosystem.<\/jats:p>","DOI":"10.1002\/anie.202219140","type":"journal-article","created":{"date-parts":[[2023,3,29]],"date-time":"2023-03-29T08:43:02Z","timestamp":1680079382000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":43,"title":["Do The Twist: Efficient Heavy\u2010Atom\u2010Free Visible Light Polymerization Facilitated by Spin\u2010Orbit Charge Transfer Inter\u2010system Crossing"],"prefix":"10.1002","volume":"62","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2500-166X","authenticated-orcid":false,"given":"Ain","family":"Uddin","sequence":"first","affiliation":[{"name":"Department of Chemistry The University of Texas at Austin  78712 Austin TX USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1511-6594","authenticated-orcid":false,"given":"Seth R.","family":"Allen","sequence":"additional","affiliation":[{"name":"Department of Chemistry The University of Texas at Austin  78712 Austin TX USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2341-1166","authenticated-orcid":false,"given":"Adrian K.","family":"Rylski","sequence":"additional","affiliation":[{"name":"Department of Chemistry The University of Texas at Austin  78712 Austin TX USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5175-1889","authenticated-orcid":false,"given":"Connor J.","family":"O'Dea","sequence":"additional","affiliation":[{"name":"Department of Chemistry The University of Texas at Austin  78712 Austin TX USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9164-508X","authenticated-orcid":false,"given":"Jack T.","family":"Ly","sequence":"additional","affiliation":[{"name":"Materials and Manufacturing Directorate Air Force Research Laboratory  45433 Wright-Patterson AFB OH USA"},{"name":"UES, Inc.  45432 Beavercreek OH USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1842-056X","authenticated-orcid":false,"given":"Tod A.","family":"Grusenmeyer","sequence":"additional","affiliation":[{"name":"Materials and Manufacturing Directorate Air Force Research Laboratory  45433 Wright-Patterson AFB OH USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3322-3687","authenticated-orcid":false,"given":"Sean T.","family":"Roberts","sequence":"additional","affiliation":[{"name":"Department of Chemistry The University of Texas at Austin  78712 Austin TX USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1013-5422","authenticated-orcid":false,"given":"Zachariah A.","family":"Page","sequence":"additional","affiliation":[{"name":"Department of Chemistry The University of Texas at Austin  78712 Austin TX USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2023,4,20]]},"reference":[{"key":"e_1_2_8_1_1","first-page":"853","volume":"11","author":"Norberg A.
